Hello girls n guys!

I am close to finishing my (very first) NAVA and got pretty far but there are still some bugs to fix, thought I might seek some help and share some insights in bugs that I fixed but seemed unsolved here in the forum!

I got my EEPROM working by putting pin 7 to ground. Now I got the every pattern has 256 steps issue BUT you can re program the steps, you just have to save everything to make it permanent and also the patterns are chained wich you also have to break up.
Unfortunally I now have to re-program every single pattern, and somehow they are all chained in a weird way by default. Any info on how to "factory reset all patterns and tracks"?

My Clap worked even before I bent leg 3, but somehow every thing that is noise related is too high in volume. Any hints? Will go and look into resistor values, but maybe this is covered?

Ride is super low and has loads of aliasing when pitched, crash has no sound. Any hints?

And on another note: is ist possible to alterate the overall maximum volume of instruments? If I just need the bassdrum to be louder?

Appreciated and happy building,

Tobi

Okay so here is the Update:

I made another Init Eeprom attempt and all the patterns are normal now. Yay!

There are some solder joints super close in the Crash / Ride section that are not meant to have continuity so fixing two joints got my Cymbals working yayyy!

This whole debugging thing turned into quite some fun when I changed R419 to get the rim volume in place and as somebody in the forum suggested I switched R205 from 3.3K to 4.7K and it got a little better - maybe someday I even try higher volume who knows at least Kick and Clap are not worlds apart in level anymore

Speaking of Kickdrums I will try to lower 501 + 502 for more Volume in the Mix out aswell as changing C153 + C154 to 10uF for more BASS!

What still bugs me is:

My Crash seems to have an odd release - it sounds choppy. Switching the Sample Chips reveals it must be somewhere in the circuit. Anyone here with any hints?

I can not program any Accent on Crash and Ride and did not find any clear info on how this is possible or not. Should I reset the firmware, is this a MUX board thing?

And lastly: My Mix out seems to be unbalanced as the left channel is roughly 9dB louder. Any hints on that?

Thanks for reading, helping and happy building! Tobi

Hello fellow builders from the future!

I checked my unbalanced output issue and measured the pot - turns out my pot is just about 10% off in the lower regions. Mäh. When I turn it up this becomes much much smaller, I don't like it but at least no issue here. Won't bother to put in another as I'll most probably just use it in mono.

I hunted down my crash release and voila - I had RA11C + RA11D swapped. They look basically the same on the board because some of the letter D is cutted by the hole, if you have a similar issue you might want to look into that.

Last thing left, despite some modding, is that I cannot program Accents for Crash, Ride and OH.
Even with the MUX boards out, so what is it?

Cheers,

Tobi

No Accent control on these instruments so everything good!

Hope my documentation helps a fellow builer or two.

Happy fault finding!
